BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a pillow for head rest, particularly to an ergonomical pillow for head rest wherein the pillow can be used to stabilize movement of user's head and provide appropriate support to user according to his/her body type.

2. Description of Related Art

Humans spend on average one-third of his/her whole lives for sleeping. Researches have shown that sleep quality may take toll on our health, for an example demonstrating such discovery, sleep has been confirmed to be the best way to regain vitality, and sufficient amount of sleep is instrumental to youth's growth. Our brain continues to give instructions during our sleep time to different parts of our body for self-regeneration in order to sustain their normal functions. As well, our brain can also put together the information and knowledge we hear and learn during the day, and restructure them so as to formulate a memory block. In summary, sleep is an indispensable and essential component of our daily lives and health, and excellent sleep quality is instrumental to maintaining a good health.

Among other possible attributing factors to sleep quality, the pillow quality itself can be an important one. However, it is to be noted here that the Chinese proverbial saying that goes as “sleeping high on tall pillow keeps worry away” is actually a misleading conception. Under normal conditions, the human body is more adaptable to maintain a natural posture where the vertebral column is kept in a straight line as looking from the front, but if viewed from a side perspective, the seven vertebrae of the cervical curve will appear in a curve in such a fashion to protrude forward. Therefore, the height of the pillow should also satisfy the arc length of such curve such that the cervical vertebrae can be maintained in a natural condition. Either a overshooting or low-pass pillow height can hardly keep the cervical vertebrae in a natural condition. This has been reported by users to be contributing to neck pain, or the so-called neck muscle spasm.

Medical experts have suggested that the pillow height for users lying with back on the floor to be kept between 5 to 8 cm as a best mode of practice. In another perspective, a majority of people cannot constantly remain in the same sleep posture while sleeping, for which the most common postures are lying on his/her back or on his/her side. As such, the most ideal pillow height, taking into consideration of each person's body type and shoulder width, gender, and age is between 8 to 10 cm. In another perspective, it is commonly known to best place the bottom edge of the pillow close to user's shoulder, and keep away from suspending the cervical vertebrae and back in mid-air. It will be understood to persons skilled in the art that such arrangement is sufficient to provide proper weight support and pressure relief.

Traditional pillows are known to be equal and symmetrical in terms of their shape, and the pillow surface used mainly for supporting user's head (particularly back of head) is a flat surface, and the majority of these traditional pillows tend not to be designed by ergonomical standards and without consideration of adapting to human body curves. Pillow surface highly suitable for back lying may appear to be slightly low for side lying. There has been proposed a memory pillow made from memory cotton, of which the central area is a flat surface, the edge of which has winding protrusions and is higher than the pillow surface such that the edge having protrusions can support weight of back of user's neck. However a disadvantage of the such design is suitable only for the back lying sleep posture because the protruding edge will become higher than the flat pillow surface in the middle, and such arrangement can cause the side of user's head (especially ears) to be turned to an inappropriate downward inclination posture.

SUMMARY OF THE INVENTION

In order to solve the aforementioned issue raised by traditional arts in the field of pillow technology and to provide better health and comfort benefits, the present invention provides an ergonomical pillow for head rest having a capability to stabilize a user's head position such that the user can be saved from undesirable neck muscle spasm, while at the same time keeping a uniform pressure relief to the user to also provide comfort and excellent sleep quality.

An embodiment of the ergonomical pillow for head rest of the present invention comprises:

-   -   a pillow surface, which is a sheet-like element made from a soft         buffer material;     -   a shock absorbing and pressure relief cushion, which is a         sheet-like element made from a shock absorbing and pressure         relief material; and     -   a pillow, wherein the pillow is made from a soft buffer         material, and has at least a hollow compartment, the hollow         compartment is located in an essential position on the pillow         for supporting the weight of a user's head, wherein when a         user's head is lying on the pillow surface sitting above the         hollow compartment, the pillow surface and shock absorbing and         pressure relief cushion will settle into the hollow compartment         due to weight of user's head. This also will guide the user to         move his/her shoulder near the bottom edge of the pillow to         avoid neck muscle spasm, and will offer comfort and excellent         sleep quality through the shock absorbing and pressure relief         cushion beneath the pillow surface.

According to an embodiment of the present invention, the pillow has a first hollow compartment and a left hollow compartment and right hollow compartment deposed respectively on the two sides of the first hollow compartment. The first hollow compartment is located on an essential location of the pillow for supporting the weight of a user's head. The first hollow compartment is suitable for use in supporting rear side of head, the depth of the left hollow compartment and right hollow compartment are smaller than the first hollow compartment, which can support head's side surface when the user is lying on his/her side. The level of settlement of head depends on the user's body type and weight, and the pillow can provide suitable support when the user is either lying on his/her side or back.

According to a structure of an embodiment of the present invention, the shock absorbing and pressure relief cushion can be made from shock absorbing and pressure relief material selected from a gel or silicon.

According to an embodiment, the soft butter material for making the pillow can be selected from foam, high density foam, and latex.

As will be understood from the above disclosure, the ergonomic pillow for head rest of the present invention has at least a hollow compartment on the main distribution location of the weight of the user's head. When the user's head is lying on the pillow surface above the hollow compartment of the pillow, the pillow surface and the shock absorbing and pressure relief cushion covering the top of the hollow compartment will settle into the hollow compartment due to weight of user's head. This type of pillow surface is capable of stabilizing user's head, and can place the head and neck in an appropriate location, and further guiding user's shoulder to be near the bottom edge of the pillow in order to avoid neck muscle spasm. In another embodiment of the present invention, hollow compartments of different depth are used, which can provide appropriate support depending on body type, and offer uniform pressure relief through the shock absorbing and pressure relief cushion beneath the pillow surface.

These features and advantages of the present invention will become fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
